That great recipe you opened at work? If you're using Chrome's Beta channel wherever you go, it's now two clicks to bring it back up, as Chrome Beta has picked up the open tab syncing already seen in Dev channels. It's rolling out in a new release today.
If you've grabbed the latest Chrome Beta, you should be able to head into your Settings, then click the "Advanced sync settings" button and see a new option for "Open tabs" (which will be checked if you've set Chrome to "Sync Everything"). Do that on other Chrome browsers you've synced to your account, and on the New Tab Page, you'll see a list in the lower-right corner: "Other Devices." Click that, and there you go—everything you last had open on other Chrome instances. If you're using the Chrome for Android Beta, you'll see those tabs on your computer, and vice-versa, too.
